JetBrains IDE Performance Config

High Performance Configuration for Jetbrains IDEs [IntelliJ, WebStorm, etc..]

Motivation

Once you step into the realm of multi-project development, large scale dev, or just have to have like 6 IDE's open. You really start to feel a performance hit on jetbrains IDEs.

This configuration aims to give at least 10x performance increases across the board.

Goals

• Faster Indexing Times
• More Responsive IntelliSense
• Less random freezing or UI lockups
• Better Memory Management
• More multi-threading
• Quicker startup time

What you need to do

The recommended way of changing the JVM options in the recent product versions is from the Help | Edit Custom VM Options menu. To change the IDE options go to *Help | Edit Custom Properties

For Older IDEs, something like this:

$ vim /Applications/IntelliJ\ IDEA\ 15.app/Contents/bin/idea.vmoptions

|- * idea.vmoptions --> Help |> Edit Custom VM Options menu |- * idea.properties --> Help |> Edit Custom Properties

idea.properties

editor.zero.latency.typing=true
idea.max.intellisense.filesize=3500
idea.cycle.buffer.size=2048
